If you ever encounter a spirit in your home and a religious item is inverted this is not a ghost. Seek religious help immediately. Do not sage your home as it will only irritate the evil spirit. Evidence again that we are not alone and I am seeing more and more infestations and diabolical hauntings as the years pass. The resolution of hauntings is a part of my practice that I have been involved in since I was sixteen and it is something I feel called to do. Once things get to this level outside assistance is needed. These types of entitles look for homes and families that may be vulnerable and then they work them. This used to be a relatively rare occurrence but it is seen much more often in our present day.
Be safe out there.
